DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 723,921, dated March 31, 1.903.

v Application filed October 6,1902. Serial No. 126,077. (llo model I T0 all whom it may concern: A

Be it known that I, JAY B. RHODES, a citizen of, the United States of America, and a resident of Harvey,Cook county, Illinois,have invented'a certain new and useful Improvementiln Dump-Cars, of which the following is a specification.

My invention rela-tes to dump-cars of the class in which a tilting body is mounted on a truck and provided at each side with a gate or displaceable side-board which automatically opens when the body tilts to one side.

Generally stated,the object of my invention by thev hooks d2, mounted on .the bolts or pins is to provide a simple, compact, and comparatively inexpensivelyconstructed dump-oar ofV the foregoing character. Y

A special object is to provide an improved form of prop for opening the gates or sideboards. A

Another object is to provide an improved form of locking device for connecting the lower ends of the said props with the truck.

Afurther object is to provide an improved form of connection between the side-boards and the body whereby the lower edge of either board may be unlocked or released before the displacement is produced, so as io permit the y bottom of the board to first swing outward.

It is also an object to provide certain details and features of improvement tending to increase the general efficiency and serviceability of a dump-car of this particular construction. Y

To the foregoing and other useful ends my invention consists -in matters hereinafterset placeable side-boards C. Each side-board is4 connected with the body by a pair of swinging arms c.' Theseswinging arms have their inner ends pivoted at 0",.while their outer ends are pivoted to the upper ends of the locking-bolts C. These bolts are arranged for vertical sliding movement in the straps or bearings c2. The lower end of each bolt is adapted to engage ano'peningbin the floor of the body. The props .Dhave their upper ends pivotally secured to the arms `c, while their lower ends are adapted to rest upon the truck. Each prop consists of a pair of bars connected'at their lower ends by a pin or bolt d. Thus the lower ends of each -pair of bars are adapted to straddle the ridge of a short length of T-iron E. The upper end of each inner bar is providedA with a bent portion d', adapted to project over the upper edge of the body. Each T-iron is provided with a link e, and these linksare adapted to be engaged d. These hooks are adapted to be clamped to the props by means of the sliding rings e2. When the body tilts to one side, as shown in Fig. l, the props at the side to which the body istilted rest upon the truck between the bolt-heads c', while the props at the other side are lifted upward away from the truck. The props resting on the truck cause the arms and the locking-bolts at that side to remain stationary, while the body and sideboard move downward. The initial movemeut o f the body'and the side-board is sufficient to disengage the lower ends the bolts from their sockets in the body, and at this point in the operation the stops c3 on the bolts engage the straps c2so as to prevent further relative movement between the side, board and the two bolts. The tilting movement now continuing, the body moves downward away from the side-board, allowing the contents of the bodyto discharge or dump at the side of the truck. It will be seen, however, that the instant the two bolts are disengaged from their sockets in. the body .the side-board is freeto swing outward at its bottom, so as to relieve the pressure on its inner surface and so as to permit a partial `discharge before the body moves downward relatively to the side-board'. In this way the partial tilting movement of the body serves to disengage the lower edge of the board be- Ifore any relative displacement is produced between. the board and the side of the boX or body. In other words, the gate or side-board is unlockedandallowed to swing outward be- IOO fore any relative sliding movement is produced between its inner surface and the load. This improved method of operation is exceedz lower ends, it follows that either side-board can be swung up and over and allowed t0 rest upon the opposite side of the body. This, it will be seen, permits either gate to be opened, so as to facilitate loading. Preferably the props do not quite rest upon the truck when the body is horizontal, as shown in Fig. l. In this Way the construction affords a slight play or lost motion between the props and the truck.

The short lengths of T-iron are preferably bolled to the sills o, by means of the bolts a. The heads of these bolts, as previously eX- plained, are preferably arranged in such manner as to provide seats for the lower ends of the bars constituting the props. Thus each prop when pressed down upon the truck has its lower end firmly held against slip or displacement.

With respect to the general operation of the car it will be seen that the locking-bolts have a positive connection with the props through the medium of the swinging arms, but have a shifting or sliding connection with the side-boards. Hence the looking devices are operated by the initial tilting movement of the body and act to release the boards before any displacement is producedthat is to say, the boards are allowed to swing outward while moving downward with the load. Thus the load has no downward-sliding movement relatively to the board whatever, and in this way there is no danger of breakage, particularly in the case of a load consisting of sharpedged rock. In other words, the locking devices act to release the boards before the ioor of the body is lowered away from their edges.

The locking devices for the lower ends of the props are, it will be seen, adapted to serve as the sole medium of connection between the truck and the lower ends of said props. In this way these locking devices are capable of totally disconnecting the lower ends of the props from the truck.
